How to grow great potatoes – 9 step potato growing guide

  1. Buy blight-resistant varieties

    Excessive wet weather can lead to the gardener’s nemesis – blight – which can ruin your crop in one fell swoop.

    But there’s a range of blight-resistant ‘superspuds’ known as Sarpos (pronounced Sharpo). Available in red, white and blue, from Thompson & Morgan, Suttons, garden centres and online retailers, they are now being grown by gardeners who don’t want the plight of blight. Blue Danube is a good blight-resistant variety with a deep blue/purple skin (but white flesh). The secret for how to grow great potatoes – start with the right variety.

  2. ‘Chit’ potatoes first

    Seed potatoes can now be bought in large bags from garden centres, seed companies and online, but if you have limited space or just want to try out a few, hunt out the centres which sell loose tubers by weight.

    Early varieties of seed potatoes should be ‘chitted’ in January and February before planting out (you don’t need to chit maincrop types as they have a longer growing season).

    Chit them by laying the potatoes rose-end (where most of the tiny sprouts are) on newspaper in clean seed trays or old egg boxes, placed on a windowsill or in a frost-free greenhouse in a light position but not in direct sunlight.

    In a few weeks, the shoots will grow, gaining strength while the soil is still too cold for them to be planted outside.

    Rub off all but the four strongest sprouts and when they have grown to around an inch, chitting is completed. Don’t plant them out until the end of March, though, as the shoots will take time to develop.Potato chtting prior to planting out

  3. Prepare the ground for planting

    In the meantime, if you have a vegetable plot or allotment, dig the area to loosen the soil, adding organic matter such as well-rotted manure or compost and working it into the soil as an essential stage in how to grow great potatoes.Prepare the ground for planting

  4. When to plant potatoes

    Early varieties can be planted out in late March and early April, second-earlies a week later, and maincrop potatoes a week after that.

    Plant tubers of seed potatoes around 15cm deep and 40cm apart in rows 60cm apart. Second earlies and maincrop potatoes should be planted 40cm apart allowing 75cm between rows.Know when to plant with our how to grow great potatoes growing guide.

  5. Potato growing guide maintenance phase

    Hoe shallowly to keep the rows weed-free, then when the first shoots appear above the surface, draw up earth with a hoe from between the rows to cover the shoots (known as earthing up), which encourages underground shoots and more tubers and stops the tubers being exposed to the surface and turning green. Earthing up will create gullies between rows.

  6. Growing phase

    Potato foliage should soon cover the ground and you won’t need to weed any more, while potatoes rarely need watering, unless you get a prolonged period of drought in summer.

    How to grow great potatoes tip: if a late frost is predicted in May, cover the foliage with garden fleece, or sacking as if the leaves are blackened, the yield may be reduced.Potato plant growing in a vegetable garden

  7. How to harvest potatoes

    Earlies should be ready from early June, second-earlies from mid-June or July, and maincrops from September through the autumn.

    Start digging earlies as soon as the tubers are a fair size. Push your hand under a plant to feel for egg-sized tubers, or lift an individual plant gently using a fork.

    The tubers should come up with it, and you can sift around in the soil for any remaining ones. If the tubers aren’t ready, push them back into the ground and give them a good watering.

  8. Harvesting earlies and maincrops

    When the plants start to flower is a good indication that the tubers are ready to harvest, although you could ease out some earlies by ferreting under the soil with your hand and pulling a few out, without pulling up the plant, which will continue growing. They should keep in a cool, airy shed in the dark, or the vegetable drawer of the fridge, for a week or more.

    Second earlies can be lifted for storage later, but try to use them before you start on the maincrops. With maincrops, leave the plants to die down completely. They keep quite well in the soil but lift them before the ground becomes really wet or else they are likely to rot.The bush of the dug out young potato lies on the ground in the garden.

  9. Storage

    Dry out maincrops in a dark shed for a couple of days before storing them in hessian or paper sacks, until required. Keep this potato growing guide handy so you can repeat the process next year!How to store potatoes
